Default = 1

PulseWidth sets the duration of energy pulses (tPW). The actual pulse duration is the contents of PulseWidth

divided by the output word rate (OWR). PulseWidth is an integer in the range of 1 to 8388607.

Default = 0

LoadMin is used to set the no load threshold. When the magnitude of the PActive register is less than LoadMin,

the active energy pulse output will be disabled. LoadMin is a two's complement value in the range of

-1.0 ≤ LoadMin < 1.0, with the binary point to the right of the MSB. Negative values are not used.

Default = 0x2F03C3 = 23.5073471

Sets the temperature channel gain. Temperature gain (TGain) is utilized to convert from one temperature scale

to another. The Celsius scale (oC) is the default. Values will be within in the range of 0 ≤ TGain < 128. The value

is represented in unsigned notation, with the binary point to the right of bit 7th MSB. See Section 5.8 On-chip

Temperature Sensor on page 19.

Default = 0xF3D35A = -0.0951126

Temperature offset (Toff) is used to remove the temperature channel’s offset at the zero-degree reading. Values

are represented in two's complement notation and in the range of -1.0 ≤ Toff < 1.0, with the binary point to the

right of the MSB.
